Description

収集ホッパー１０の下流端部１０．２は、第一の部位１２の動きに対する軸方向の停止手段を形成するように、支持リング１８の内側に突出する半径方向の表面２９と協働する外部肩部２７を含む。また、この接触は、金属同士のシールを形成する。半径方向の表面２９は、第一の部位を収集ホッパー１０に取り付け可能とする脱着式リングにより支持される。 The downstream end 10.2 of the collection hopper 10 is an outer shoulder that cooperates with a radial surface 29 projecting inward of the support ring 18 to form an axial stop for movement of the first portion 12. Part 27 is included. This contact also forms a metal-to-metal seal. The radial surface 29 is supported by a removable ring that allows the first site to be attached to the collection hopper 10 .

取り付けフランジ４６は、有利に固定され、第一の部位から容易に分離可能であり、従って、蛇腹の容易な交換が可能である。図例では、固定手段は、バヨネットタイプである。第一の部位は、ロッドと、第一の部位の下流面から突出する頭部とから形成される突起５２を含み、取り付けフランジ４６は、装置への挿入を可能とするため、ロッドの直径の幅に近いより小さい幅の部位と、ヘッドの直径に近いより大きい幅の部位と含む、開口５４を含む。組み立てのためには、突起は、捕捉部をより小さい幅の部位に位置するように、より大きい幅の部位に単に挿入され、続いて、取り付けられたフランジ４６が第一の部位１２に対して軸を中心に回転される。 The mounting flange 46 is advantageously fixed and easily separable from the first site, thus allowing easy replacement of the bellows. In the illustrated example, the fixing means is a bayonet type. The first part includes a protrusion 52 formed from a rod and a head projecting from the downstream surface of the first part, and the mounting flange 46 allows for the insertion of the rod diameter to allow insertion into the device. An opening 54 is included that includes a smaller width portion near the width and a larger width portion near the head diameter. For assembly, the protrusion is simply inserted into the larger width portion so that the catch is located at the smaller width portion, and subsequently the attached flange 46 is relative to the first portion 12. It is rotated around the axis.

ある距離の移動後に、シールリング１４の支持面は、ジャーのネックに接触する。支持リング１８は、ピン２４がシールリング１４の肩部３２から離れるまで、その移動を続ける。そして、図２Ａ及び図２Ｂ（シール状態）で確認できるように、シールリング１４は分離され、ネックに載り、重力の影響下においてその重量がシール縁部３０をジャーのネック８に圧して、密な接触をもたらす。図１では、シール縁部３０は、押圧されない状態である。 After a certain distance of movement, the support surface of the seal ring 14 contacts the neck of the jar. The support ring 18 continues to move until the pin 24 moves away from the shoulder 32 of the seal ring 14 . 2A and 2B (sealed state), the seal ring 14 is separated and rests on the neck, and under the influence of gravity, the weight presses the seal edge 30 against the neck 8 of the jar and closes it tightly. To make a good contact. In FIG. 1, the seal edge 30 is not pressed.

第一の部位１２を上昇することによりジャーが離れ、第一の部位は、ある距離の移動後、ピン２４と接触し、これがシールリング１４を持ち上げ、シールリングはジャーのネックから離れる。第一の部位１２の上昇は、長い距離に亘って生じ、ジャーのシールリングを十分に離すことが可能である。続いて、ジャーは計量器から撤収され、運搬機で運ばれる。 Raising the first part 12 leaves the jar, which after a distance travels in contact with the pin 24, which lifts the seal ring 14 away from the neck of the jar. The elevation of the first portion 12 occurs over a long distance and can sufficiently release the seal ring of the jar. Subsequently, the jar is withdrawn from the scale and transported by a transporter.

連結装置の維持は、簡単である。従って、蛇腹４２の交換は容易である。実際には、回転により取り付けフランジ４６を第一の部位１２から外し、クランプ結合部４８、５０を外すことによりシールリング１４及び取り付けフフランジ４６を蛇腹４２から分離するだけでよい。フランジ４６を第一の部位１２から外す前に、フランジ４６とシールリング１４とが、例えば横断軸に沿って互いに近づけられた後に固定されることが好ましい。蛇腹４２は圧縮され、シールリング１４の重さによる延長により損傷を受ける危険性がなくなる。 Maintenance of the coupling device is simple. Therefore, the bellows 42 can be easily replaced. In practice, it is only necessary to remove the mounting flange 46 from the first portion 12 by rotation and to separate the seal ring 14 and the mounting flange 46 from the bellows 42 by removing the clamp couplings 48, 50. Prior to removing the flange 46 from the first portion 12, the flange 46 and the seal ring 14 are preferably secured after being brought closer together, for example along the transverse axis. The bellows 42 is compressed, eliminating the risk of damage due to extension due to the weight of the seal ring 14 .
